Putter

Abstract

When hitting a ball to a target with a putter, the ball often travels to a point which is deviated to the right from the target. When a golfer looks at the target just after taking his address, he turns his head to a target about a rotation axis which extends through the back of his head. When this rotation axis is not horizontal and an angle defined by the rotation axis and his sighting line to a putter head is not 90°, he has an optical illusion which tricks him into believing that he has to correct his address position. The putter of the present invention is provided with a thin-plate pendulum thereby allowing him to turn his head about the rotation axis while keeping the angle defined by the rotation axis and his sighting line at 90°.

AI Technical Summary

Benefits of technology

[0007]The object of the present invention is to provide a putter which allows a golfer to putt a ball accurately to the target by eliminating optical illusion which tends to occur with respect to a target direction of putting.

[0050]And, when lighting and light-collecting function is provided, the golfer can check precisely how a sheet pendulum is in the putter head.

Problems solved by technology

This caused a problem that the golfer could strike the ball for proper distance with ball rolling smoothly, but as a result, the ball arrived at the point deviated to the right from the target, while the golfer who putted the ball did not understand the reason why an intended target line is deviated from the target.
